Description

Technical Field

[0001] This utility model relates to an ozone catalytic oxidation system, belonging to the field of wastewater treatment technology. Background Technology

[0002] Ozone catalytic oxidation technology is based on advanced ozone oxidation technology, combining the strong oxidizing properties of ozone with the catalytic characteristics of catalysts. It utilizes highly reactive free radical intermediates generated by ozone molecules on the catalyst surface, especially hydroxyl radicals, to oxidize and remove recalcitrant organic matter from wastewater, effectively addressing the problem of incomplete organic matter degradation. It shows significant effects in wastewater treatment, including COD reduction, ammonia nitrogen removal, decolorization and denitrification, reverse osmosis concentrate generation, upgrading and retrofitting, landfill leachate treatment, coking wastewater treatment, and exhaust gas deodorization.

[0003] When using ozone catalytic oxidation technology to treat wastewater, ozone and catalysts need to be added to degrade the wastewater. However, when using ozone to treat wastewater, a large amount of ozone and a long base time are required to achieve the oxidation effect. Increasing the amount of ozone will inevitably increase the cost of wastewater treatment, and extending the ozone treatment time will inevitably result in low wastewater treatment efficiency and low ozone utilization.

[0004] Therefore, in order to improve the ozone oxidation effect and reduce the cost of wastewater treatment, there is an urgent need for an ozone catalytic oxidation system. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an ozone catalytic oxidation system. After the wastewater settles in the sedimentation tank, the electromagnetic activation component can change the cluster structure, properties and ozone dissolving capacity of the wastewater. Then, it is discharged into the catalytic oxidation reaction component to carry out the catalytic oxidation reaction, so that the ozone, wastewater and catalyst are in uniform contact, achieving the effect of efficient decomposition of organic matter in wastewater. After the catalytic oxidation is completed, the treated wastewater enters the aeration component through the pipeline for aeration treatment, and is discharged after aeration treatment.

[0006] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution:

[0007] An ozone catalytic oxidation system includes a sedimentation tank, an electromagnetic activation component, an ozone generator, a catalytic oxidation reaction component, and an aeration component, wherein...

[0008] The output end of the sedimentation tank is connected to the input end of the electromagnetic activation component, the output end of the electromagnetic activation component is connected to the input end of the catalytic oxidation reaction component, and the output end of the catalytic reaction component is connected to the aeration component.

[0009] The catalytic oxidation reaction assembly is equipped with multiple sets of aeration ring pipes. These multiple sets of aeration ring pipes are installed inside the catalytic oxidation reaction assembly via a lifting assembly. The multiple sets of aeration ring pipes are connected to the output end of the ozone generator via pipes, and a catalyst is provided between each aeration ring pipe.

[0010] Furthermore, the electromagnetic activation component is a high-frequency electronic water processor.

[0011] Furthermore, the lifting assembly includes a drive motor and a threaded shaft. One end of the threaded shaft is rotatably connected to the inner top wall of the catalytic oxidation reaction assembly housing, and the other end passes through the inner top wall of the catalytic oxidation reaction assembly housing and is driven by the drive motor. A synchronization sleeve is threaded onto the threaded shaft, and the aeration ring pipe is fixed on the synchronization sleeve.

[0012] Furthermore, it also includes a limiting block, one end of which is connected to the side wall of the aeration ring pipe, and the other end is slidably connected to the inner side wall of the catalytic oxidation reaction component housing.

[0013] Furthermore, it also includes stirring blades, which are fixed on a threaded shaft.

[0014] Furthermore, the distance between the aeration rings is not less than 50cm, and the catalyst is installed on the inner wall of the catalytic oxidation reaction component housing through the catalytic chamber.

[0015] Furthermore, the surface of the aeration ring pipe is provided with a plurality of aeration micropores, which face the catalytic chamber.

[0016] Furthermore, it also includes an ozone detector and a digestion tank. The top of the catalytic oxidation reaction component is connected to the digestion tank via a pipe, and the ozone detector is installed on the catalytic oxidation reaction component.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0018] The ozone catalytic oxidation system provided by this utility model involves wastewater settling in a sedimentation tank. An electromagnetic activation component alters the cluster structure, properties, and ozone dissolving capacity of the wastewater before it is discharged into a catalytic oxidation reaction component for further catalytic oxidation. Since the aeration ring pipe in the catalytic oxidation component is connected to an ozone generator via a pipeline, ozone can diffuse throughout the chamber of the catalytic oxidation reaction component during the catalytic reaction. The lifting component effectively enhances the ozone's effective range, ensuring optimal contact between ozone, wastewater, and the catalyst. This results in uniform contact between ozone, wastewater, and the catalyst, achieving efficient decomposition of organic matter in the wastewater. After catalytic oxidation, the treated wastewater enters the aeration component through a pipeline for aeration treatment before being discharged.

[0019] The ozone catalytic oxidation system provided by this utility model can further increase the contact effect between ozone and wastewater and catalyst by adding stirring blades to the lifting component, so that ozone can be in uniform contact with wastewater and catalyst, and achieve the effect of efficient decomposition of organic matter in wastewater.

[0020] The ozone catalytic oxidation system provided by this utility model sets an ozone detector and a digestion tank at the top of the catalytic oxidation reaction component. The ozone detector detects the ozone content accumulated at the top of the inner cavity. If the ozone content reaches the national emission standard, it will be directly emitted.

[0021] The ozone catalytic oxidation system provided by this utility model can eliminate ozone that does not meet the national emission standards through a decomposition tank if the ozone content does not meet the emission standards. This can safely eliminate excess ozone and ensure the safe operation of the device. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0027] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0029] This embodiment provides an ozone catalytic oxidation system, comprising a sedimentation tank 1, an electromagnetic activation component 2, an ozone generator 3, a catalytic oxidation reaction component 4, and an aeration component 5, wherein...

[0030] The output end of the sedimentation tank 1 is connected to the input end of the electromagnetic activation component 2, the output end of the electromagnetic activation component 2 is connected to the input end of the catalytic oxidation reaction component 4, and the output end of the catalytic reaction component is connected to the aeration component 5.

[0031] The catalytic oxidation reaction component 4 is equipped with multiple sets of aeration ring pipes 7. The multiple sets of aeration ring pipes 7 are installed in the catalytic oxidation reaction component 4 through lifting components 6. The multiple sets of aeration ring pipes 7 are connected to the output end of the ozone generator 3 through pipes, and a catalyst is provided between each aeration ring pipe 7.

[0032] In the above technical solution, after the wastewater settles in the sedimentation tank 1, the electromagnetic activation component 2 can change the cluster structure, properties, and ozone dissolving capacity of the wastewater. Then, it is discharged into the catalytic oxidation reaction component 4 for catalytic oxidation reaction. Since the aeration ring pipe 7 in the catalytic oxidation component 4 is connected to the ozone generator 3 through a pipeline, ozone can be dispersed in the chamber of the catalytic oxidation reaction component 4 during the catalytic reaction. The setting of the lifting component 6 can effectively improve the range of ozone action, ensure the contact effect of ozone with wastewater and catalyst, and make ozone contact wastewater and catalyst evenly, so as to achieve the effect of efficient decomposition of organic matter in wastewater. After the catalytic oxidation is completed, the treated wastewater enters the aeration component 5 through a pipeline for aeration treatment, and is discharged after aeration treatment.

[0033] like Figure 2 As shown, part of the pipe connecting the aeration ring pipe 7 and the ozone generator 3 is a corrugated pipe structure, which can meet the adjustment requirements of the lifting component 6 during lifting. Example 2

[0034] The ozone catalytic oxidation system provided in this embodiment differs from the ozone catalytic oxidation system provided in Embodiment 1 in that:

[0035] To achieve the treatment of sewage by the electromagnetic activation component 2, the electromagnetic activation component 2 is a high-frequency electronic water processor. The high-frequency electronic water processor uses the principle of electromagnetic shear to apply a high-frequency electromagnetic field instantaneous shear to the cluster structure of water molecules, organic molecules, and ions in the sewage, thereby breaking the cluster structure of various micro-morphological bodies in the sewage, breaking the hydration and association effects of water molecules, organic molecules, and ions, and changing the physical, chemical, and molecular mechanical properties of the sewage.

[0036] To enable the lifting component 6 to drive the aeration ring pipe 7 to move up and down, the lifting component 6 includes a drive motor 601 and a threaded shaft 602. One end of the threaded shaft 602 is rotatably connected to the inner top wall of the catalytic oxidation reaction component 4 housing, and the other end passes through the inner top wall of the catalytic oxidation reaction component 4 housing and is driven by the drive motor 601. A synchronization sleeve 603 is threadedly installed on the threaded shaft 602, and the aeration ring pipe 7 is fixed on the synchronization sleeve 603. Through the reciprocating rotation of the drive motor 601, the aeration ring pipe 7 can be reciprocated up and down, thereby increasing the ozone effect range.

[0037] To ensure the stability of the aeration ring pipe 7 during reciprocating lifting and lowering, a limiting block 604 is also included. One end of the limiting block 604 is connected to the side wall of the aeration ring pipe 7, and the other end is slidably connected to the inner side wall of the catalytic oxidation reaction component 4 housing.

[0038] To further increase the range of ozone's effect, a stirring blade 605 is also included, which is fixed on the threaded shaft 602.

[0039] To avoid motion interference during the raising and lowering of the aeration ring pipes 7, the distance between the aeration ring pipes 7 is not less than 50cm. The catalyst is installed on the inner wall of the catalytic oxidation reaction component 4 through the catalytic chamber 8. Under normal circumstances, the catalyst between the two aeration ring pipes 7 is located in the middle position. Therefore, the raising and lowering distance of the aeration ring pipes 7 is limited, and the raising and lowering height is not greater than 10cm.

[0040] like Figure 3 As shown, the surface of the catalytic chamber 8 is provided with several holes for wastewater to pass through and react with the catalyst in the chamber. The connecting pipe between the catalytic chamber 8 and the aeration ring pipe 7, as well as the corresponding location of the threaded shaft 602, are provided with through holes for passage.

[0041] To ensure the aeration effect, the surface of the aeration ring pipe 7 is provided with a number of aeration micropores, which face the catalytic chamber 8.

[0042] To facilitate the subsequent removal of ozone from the catalytic oxidation reaction assembly 4, an ozone detector 9 and a digestion tank 10 are also included. The top of the catalytic oxidation reaction assembly 4 is connected to the digestion tank 10 through a pipe, and the ozone detector 9 is installed on the catalytic oxidation reaction assembly 4.

[0043] After ozone enters the inner cavity of the ozone catalytic oxidation reactor assembly 4, it accumulates at the top of the cavity. The ozone content at the top of the cavity is detected by the ozone detector 9. If the ozone content meets the national emission standards, it will be directly discharged (the top of the ozone catalytic oxidation reactor assembly 4 is equipped with a separate discharge pipe with a valve; when the content meets the standard, the valve is opened directly and the ozone is discharged through this pipe). If the ozone content does not meet the national emission standards, it will be treated by the decomposition tank 10 to decompose the ozone that does not meet the emission standards (a valve is also installed on the pipe connected to the decomposition tank 10; when the standard is not met, the valve is opened, and the ozone enters the decomposition tank 10 through the pipe). This can safely decompose excess ozone and ensure the safe operation of the device.

[0044] In summary, the ozone catalytic oxidation system provided in this embodiment, by adding stirring blades 605 to the lifting assembly 6, can further enhance the contact effect between ozone and wastewater and catalyst, ensuring uniform contact between ozone and wastewater and catalyst, and achieving efficient decomposition of organic matter in wastewater. By setting an ozone detector 9 and a digestion tank at the top of the catalytic oxidation reaction assembly 4, the ozone detector 9 detects the ozone content accumulated at the top of the inner cavity. If the ozone content meets the national emission standards, it will be directly emitted; if the ozone content does not meet the national emission standards, the ozone that does not meet the emission standards will be digested in the digestion tank 10. This ensures the safe digestion of excess ozone and guarantees the safe operation of the device.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
